I was at the mall with friends and saw my step-dad in the car with a woman that was not my mom. They got married a year ago! My first reaction was sad for my mom that she might get her heart broken. But, my second reaction was more surprising. I was jealous that I wasn't in that car with him. That his hands weren't reaching down MY silk blouse in broad daylight. I felt angry and felt my pussy twitch in my panties as a little moisture soaked the crotch of white cotton panties. I had the perfect plan.I confronted him and told him that I saw him in the car with that strange woman. I told him that I didn't want mom to get hurt and that if he promised to not cheat on mom anymore, that I promise to make sure his Daddy needs were taken care of. I laid him on the bed and pulled off his pants. I spit my warm saliva on his cock and could feel it get harder when I did. Stroking, squeezing, pulling his cock I showed him my young tits with my big brown nipples. I told him I would take care of him whenever he wanted. It was so unbelievably hot like when I would play with my wet pussy listening to him fuck my mom at night. Begging for his big load he gave it to me because he is a good Daddy that just needs some extra attention. You're welcome Mom.
